There was a batch of affected parts that may or may not manifest problems. Yeah, it sucks that it's a cylinder head, but you know what? Nobody's Jeep is catching fire. Nobody is dying.

Let's not pretend this problem, which so far is impacting about 2% of the people with early 2012s and nobody else, is the end of the world.

No they're not but when the dealer is "fixing" them and the problem seems to come back thats troubling. If it really is a small number of Penstars, thats good.
Hopefully they get a permanent fix for this and it doesn't turn into the OPDA problem of the 05-06's.

Nobody has any idea how many have exhibited problems. It's somewhere between 0 and 100%, and since it's never hit the news it's probably closer to the low end. It's not a safety issue so we'll probably never get any hard info.

A head is never acceptable on a new or newer engine, but I've seen issues similar as a new platform is introduced. I still have not seen this as a widespread issue at all. My remark on the 3.8 is from a driveability and maintainable stand point. Having owned the 3.8 I would never be cursed with it again.

I agree completely. They really messed up with the gearing on the 3.8 making drivability not all that great.
